Wet wipe packaging body

ABSTRACT

A wet-wipe packaging-body capable of reducing costs for manufacturing the wet-wipe packaging-body and costs for managing and storing components, and solving complexity in managing and storing the components. In a wet-wipe packaging-body in which a wet-wipe body continuously stacked in a folded state is accommodated in a bag-body, an outlet port frame attached to an opening portion of the bag-body has an outlet port frame main-body provided with a resistance application member and a flange portion formed to outwardly project from the outlet port frame main-body in its radial direction. The flange portion has a first surface bonded to an inner surface of the bag-body when the outlet port frame is attached and fixed to the inner portion of the bag-body and a second surface bonded to an outer surface of the bag-body when the outlet port frame is attached and fixed to the outer portion of the bag-body.

TECHNICAL FIELD

The present invention relates to a wet wipe packaging body in which a wet wipe stacked body is accommodated in a bag body.

BACKGROUND ART

Generally, in a wet wipe packaging body, a wet wipe continuous body in which a plurality of wet wipes is connected in series to each other so as to be separable is accommodated in a container. When the wet wipes are taken out, they are pulled out one by one from the container. Conventionally, bottle-type wet wipe packaging bodies in which a wet wipe continuous body is accommodated in a cylindrical bottle have been widely used. In recent years, not only the bottle-type wet wipe packaging bodies but wet wipe packaging bodies, the accommodation container of which is formed into a bag shape such as a substantially rectangular shape or a pillow shape, have been widely used.

In the wet wipe packaging body, the accommodation container of which is formed into a bag shape, a wet wipe stacked body obtained by folding a plurality of independent sheet wet wipes is accommodated in a bag body. The plurality of independent sheet wet wipes are formed in such a way that the tip ends of the sheet wet wipes adjacent to each other are overlapped with each other and portions other than the vicinities of the tip ends are folded and overlapped with each other. The bag body has an opening portion used to outwardly pull out the wet wipes from the sides of the tip ends. In recent years, wet wipe packaging bodies have an outlet port frame at the opening portion of a bag body to separate respective wet wipes constituting a wet wipe stacked body when the wet wipes are pulled out from the opening portion. The outlet port frame has a resistance application hole formed into a shape such as to apply resistance to the pulled-out wet wipe when the wet wipes outwardly pulled out from the opening portion of the bag body are outwardly taken out, and has a cover body by which an outlet port used to take out the wet wipes is opened and closed. The outlet port frame is configured such that, when the wet wipes are pulled out, a pulled-out wet wipe is separated from the following wet wipe by a resistance force that is applied on the wet wipe as the wet wipe passes through the resistance application hole.

As wet wipe packaging bodies, a type (inner bonding type) in which an outlet port frame is attached on the inner side of a bag body and a type (outer bonding type) in which an outlet port frame is attached on the outer side of a bag body have been known (for example, Patent Document 1). In the wet wipe packaging body of the outer bonding type, the outlet port frame is attached on the outer side of the bag body by an adhesive, a gluing agent, or the like with its outlet hole aligned with the opening portion of the bag body. Since the outlet port frame is attached on the outer side of the bag body as described above, the wet wipe packaging body of the outer bonding type can be easily manufactured and produced on a large scale. On the other hand, the wet wipe packaging body of the outer bonding type requires, in its unused state in which the wet wipe packaging body has not been used by a user, bonding of a flap seal to close the opening portion of the bag body, implementation of a half-cut process with respect to the area of the opening portion of the bag body, the use of an adhesive to attach the outlet port frame to the bag body, or the like. As a result, there is a likelihood that costs for manufacturing the wet wipe packaging body are increased.

In the wet wipe packaging body of the inner bonding type, the outlet port frame is attached on the inner side of the bag body by a method such as heat sealing with its outlet port aligned with the opening portion of the bag body. In the wet wipe packaging body of the inner bonding type, the outlet port frame is generally attached so as to project from the inner surface of the bag body to the outer side of the opening portion. Therefore, the wet wipe packaging body of the inner bonding type does not require an adhesive used to bond the outlet port frame to the bag body, the bonding of a flap seal to close the opening portion, and the implementation of a half-cult process with respect to the area of the opening portion of the bag body. As a result, costs for manufacturing the wet wipe packaging body of the inner bonding type can be reduced. On the other hand, in the wet wipe packaging body of the inner bonding type, the outlet port frame is attached on the inner side of the bag body while being caused to project from the opening portion of the bag body to the outer side. Therefore, the wet wipe packaging body of the inner bonding type requires higher positioning accuracy in attaching the outlet port frame to the bag body than the wet wipe packaging body of the outer bonding type, and thus there is a likelihood that the manufacturing of the wet wipe packaging body of the inner bonding type becomes time-consuming since the attachment operation requires accuracy and carefulness.

SUMMARY OF THE INVENTION

As described above, the wet wipe packaging body of the inner bonding type and the wet wipe packaging body of the outer bonding type have their own advantages and disadvantages, and their steps of attaching the outlet port frame to the bag body are also different. Further, since the outlet port frame used in the wet wipe packaging body of the inner bonding type and the outlet port frame used in the wet wipe packaging body of the outer bonding type are different in configuration, they are required to be separately manufactured.

Further, in any of the wet wipe packaging body of the inner bonding type and wet wipe packaging body of the outer bonding type, various outlet port frames are required to suit differences in the shape and the size of the opening portion of the bag body, which gives rise to the problem that costs for manufacturing the many outlet port frames and complicated works and costs for managing and storing different components are incurred. In recent years, the problem has become particularly significant under circumstances in which various wet wipe packaging bodies have been distributed to the market.

The present invention has been made in view of the problems described above and has an object of providing a wet wipe packaging body capable of reducing costs for manufacturing the wet wipe packaging body and costs for managing and storing components and solving complexity in managing and storing the components.

The substances of the present invention are as follows:

(1) A wet wipe packaging body having a wet wipe stacked body obtained by folding a plurality of independent sheet wet wipes, a bag body that accommodates the wet wipe stacked body and has an opening portion used to take out the accommodated wet wipes, and an outlet port frame having an outlet port used to outwardly take out the wet wipes pulled out from the opening portion, wherein the outlet port frame has an outlet port frame main body provided with a resistance application member having a resistance application hole used to apply resistance to the wet wipes pulled out toward the outlet opening and a flange portion formed to outwardly project from the outlet port frame main body in a radial direction thereof, and the flange portion has a first bonding surface bonded to an inner surface of the bag body when the outlet port frame is attached and fixed to an inner portion of the bag body and a second bonding surface bonded to an outer surface of the bag body when the outlet port frame is attached and fixed to an outer portion of the bag body;

(2) The wet wipe packaging body according to the above note (1), wherein the resistance application member is configured such that at least a portion thereof where the resistance application hole is formed moves in a direction in which the wet wipe stacked body is biased, in accordance with an amount of reduction of bulk of the wet wipe stacked body resulting from pulling out the wet wipes from the outlet port, thereby biasing the wet wipe stacked body;

(3) The wet wipe packaging body according to the above note (1) or (2), wherein one end of the resistance application member is configured as a support end supported by the outlet port frame, and the other end thereof is configured as a free end pressed against a front surface of the wet wipe stacked body by the biasing force;

(4) The wet wipe packaging body according to any of the above notes (1) to (3), wherein the outlet port frame main body has one surface formed to be set at a position at which the one surface is higher than the first bonding surface in a height direction and the other surface formed to be set at a same position as the second bonding surface in the height direction; and

(5) The wet wipe packaging body according to any of the above notes (1) to (4), the wet wipe packaging body having a cover body attached to the outlet port frame and used to open and close the outlet port, wherein the cover body has a holding portion that locks the resistance application member in the outlet port frame against the biasing force, the resistance application member has a holding reception portion freely engaged with and disengaged from the holding portion, and the resistance application member is configured to be held by the cover body when the holding reception portion is engaged with the holding portion.

According to the present invention, the flange portion of the outlet port frame has the first bonding surface and the second bonding surface. Therefore, in a case in which the wet wipe packaging body of the inner bonding type is manufactured, the first bonding surface of the outlet port frame is boned to the inner surface of the bag body. In a case in which the wet wipe packaging body of the outer bonding type is manufactured, the second bonding surface of the outlet port frame is bonded to the outer surface of the bag body. In this way, the outlet port frame alone can be applied to both the wet wipe packaging body of the inner bonding type and the wet wipe packaging body of the outer bonding type. Thus, according to the present invention, the outlet port frame can be given versatility, costs for managing and storing the components of the outlet port frame can be remarkably reduced, costs for manufacturing the wet wipe packaging body can be remarkably reduced, and the wet wipe packaging body can be offered at low costs.

DESCRIPTION OF THE EMBODIMENTS

A description will be given in detail of a wet wipe packaging body according to the present invention with reference to the drawings. As shown in FIG. 1, a wet wipe packaging body 1 has a bag body 3 in which an opening portion 2 is formed to be opened and an outlet port frame 4 attached and fixed to the bag body 3 from an outer side. The bag body 3 is sealed at its open area other than the opening portion 2 by heat sealing or the like using a flexible plastic film or the like having air-tightness and is formed into, for example, a pillow-like bag shape. The bag body 3 may be made of a plastic film having a single-layered structure or may be made of a layered film or the like having a plurality of layers.

As shown in FIG. 2, a wet wipe stacked body 5 is accommodated in the bag body 3. The wet wipe stacked body 5 is one obtained by folding a wet wipe continuous body in which a plurality of independent sheet wet wipes adjacent to each other are overlapped with each other at their ends. The wet wipe continuous body 6 is folded by so-called Z-folding, W-folding, WZ-folding, or the like but is not limited to such folding methods. Thus, when the tip end portion of the wet wipe continuous body 6 is outwardly pulled out from the opening portion 2, the rear end of the pulled-out wet wipe continuous body 6 is not brought into contact with the tip end of the wet wipe continuous body 6 stacked in the next place, whereby a single wet wipe is separated from the wet wipe continuous body 6. The wet wipe continuous body 6 is base cloth impregnated with a medicine or the like. A paper, woven cloth, non-woven cloth, or the like made of, for example, synthetic fibers or natural fibers is used as a base cloth material, but the wet wipe continuous body 6 may be made of other materials. Further, examples of a medical solution or the like include alcohols, water, or their mixtures. However, a perfume, an antibacterial agent, a deodorizing agent, a surfactant, an antiseptic, a pigment, a defoaming agent, an antioxidant, a clarifier, a solubilizing agent, or the like may be blended together, or other medical solutions or the like may be used.

The opening portion 2 is formed to be opened at the central area of one of the largest surfaces of the bag body 3 to outwardly pull out the tip end portion of the wet wipe continuous body 6. An outlet port frame 4 made of a plastic material or the like having rigidity is attached to the opening portion 2 from the outer side of the bag body 3. The opening portion 2 is tightly closed by a flap seal 7 bonded to an outer surface 3 a of the bag body 3. As shown in FIG. 3, the flap seal 7 is configured to be folded in two by a folding back portion 8 and doubly overlapped with each other in a vertical direction. A sealing surface 9 on the lower side of the flap seal 7 is formed to have a size at which the entire opening portion 2 can be tightly closed. Further, a picking-up piece 10 on the upper side of the sealing surface 9 is formed to be narrower than the sealing surface 9 and configured as a picking-up portion to peel the sealing surface 9. Further, the end of the picking-up piece 10 at a position away from the folding back portion 8 is formed to slightly outwardly project from the outer circumference of the sealing surface 9 so as to be easily picked up by fingers.

As shown in FIG. 2, the lower surface (rear surface) of the sealing surface 9 of the flap seal 7 is bonded to an outer surface 3 a of the bag body 3, and the opening portion 2 of the wet wipe packaging body 1 that is not in use is tightly closed by the flap seal 7. This results in advantages such as preventing the drying of the wet wipe stacked body 5 in the bag body 3 even in a case in which the wet wipe packaging body 1 is preserved for a long time and making an adhesive that bonds the outlet port frame 4 to the bag body 3 be free from the adverse effect of the vapors of a medicine or the like from the wet wipe stacked body 5. Note that the flap seal 7 is not limited to the above shape but may have a configuration in which the sealing surface 9 and the picking-up piece 10 are formed as separate bodies and joined together at the folding back portion 8, or the like.

The outlet port frame 4 is a ring-shaped member attached and fixed to the bag body 3 by a method such as heat sealing. The outlet port frame 4 has an outlet port frame main body 11, a cover body 12, and a flange portion 13. The outlet port frame main body 11 has a peripheral wall portion 14 formed into a ring shape, an outlet port 16 formed to be opened at an inner region 15 surrounded by the peripheral wall portion 14, and a resistance application member 17 formed at the inner region 15. Note that although the outlet port frame 4 of the embodiment is formed into, for example, a ring shape such as a circular or elliptical shape, it may be formed into a shape other than the above shapes.

The peripheral wall portion 14 has an upper surface 18 as one surface and a lower surface 19 as the other surface. The upper surface 18 is formed to be set at a position at which it is vertically higher than a first bonding surface 24, which will be described later, of the flange portion 13 in a height direction, and the lower surface 19 is formed to be set at the same position as a second bonding surface 25, which will be described later, of the flange portion 13 in the height direction. Note that as for a positional relationship in the height direction between the lower surface 19 and the second bonding surface 25, the lower surface 19 and the second bonding surface 25 are not necessarily set at the same position in the height direction so long as the lower surface 19 is set at a position higher than the second bonding surface 25 in the height direction.

Further, the cover body 12 is provided at part of the upper surface 18 of the peripheral wall portion 14. The cover body 12 is openably and closably attached such that the opening portion 2 can be opened and closed from the outer side. Although not shown in the figures, the cover body 12 has a fitting piece, which is fitted over the circumference of the ring-shaped outer marginal portion of the peripheral wall portion 14 when the cover body 12 is closed, at a surface on its side brought into contact with the upper surface 18 of the peripheral wall portion 14, and is configured to be capable of closing an outlet port 16 formed on the inner side of the peripheral wall portion 14. In the embodiment, the outlet port frame 4 and the cover body 12 are integrally molded with each other by, for example, a thermoplastic resin such as polyethylene and polypropylene via a hinge portion 20 serving as a shaft for rotational movements. However, the outlet port frame 4 and the cover body 12 may be configured to be formed as separate bodies and combined with each other. Note that FIG. 2 shows a state, in which the cover body 12 has been closed to close the outlet port frame 4, by solid lines and shows a state, in which the cover body 12 has been opened to open the outlet port frame 4, by chain double-dashed lines.

As shown in FIG. 1, FIG. 2, or the like, the cover body 12 has holding portions 21 to lock the resistance application member 17 in the outlet port frame 4 against a biasing force. The holding portions 21 are formed to be capable of being fitted in engagement holes 22 serving as holding reception portions formed in the resistance application member 17 and configured to attract the resistance application member 17 to the vicinity of the cover body 12 and hold the same. With the configuration described above, the outlet port frame 4 can be smoothly attached to the bag body 3 by the downwardly-projecting resistance application member 17 when the outlet port frame 4 is adhered to the bag body 3. The state is held until the cover body 12 is first opened after the manufacturing of the wet wipe packaging body 1. Once the cover body 12 is opened, the holding portions 21 are configured to be disengaged from the engagement holes 22 to release the state in which the resistance application member 17 is held by the cover body 12. Note that the engagement between the holding portions 21 and the engagement holes 22 may be released in conjunction with, for example, the opening operation of the cover body 12 or may be released by the fingers or the like of a user without working with the opening operation of the cover body 12.

The outlet port 16 is formed to be opened at the inner region 15 surrounded by the peripheral wall portion 14 such that a wet wipe pulled out from the opening portion 2 can be taken outward. In the embodiment, the opening of the outlet port 16 is formed to have a size enough to cover the entire inner region 15, but the size of the outlet port 16 may be arbitrarily determined.

The resistance application member 17 is arranged in the inner region 15 and has a resistance application hole 23 used to apply resistance to the passing-through wet wipe continuous body 6. The resistance application hole 23 is well known. When the wet wipe continuous body 6 is pulled outwardly from the bag body 3, frictional resistance is applied to the wet wipe continuous body 6, which passes through the inner side of the resistance application hole 23, from the resistance application hole 23. Thus, the wet wipe continuous body 6 is separated at its separation allowing portion at a position at which the wet wipe continuous body 6 has just passed through the resistance application hole 23, and the wet wipe continuous body 6, which is positioned ahead of the separation allowing portion and covers an area from its tip end portion to the separation allowing portion, is taken out as a single wet wipe. Then, the outermost tip end portion of the wet wipe continuous body 6 left behind the taken-out wet wipe is held in a state of slightly outwardly projecting from the resistance application hole 23. Note that the resistance application hole 23 has various known shapes and may employ any of the shapes. Further, the resistance application hole 23 may have any shape other than the known ones so long as resistance, by which a single wet wipe can be separated from the wet wipe continuous body 6 and the tip end portion of the wet wipe continuous body 6 in the next place can be held, can be applied to the wet wipe continuous body. As described above, the resistance application member 17 has the engagement holes 22 in which the holding portions 21 of the cover body 12 are fitted.

The resistance application member 17 having the resistance application hole 23 as described above is formed to be integrated with or separated from the outlet port frame 4 and brought into a so-called cantilevered state in which only one end side of the resistance application portion is fixed to the outlet port frame 4. Further, the free end side of the resistance application member 17 is biased so as to enter the bag body 3 via the opening portion 2. In the embodiment, the resistance application member 17 has a biasing force generated from its own elasticity. However, an elastic member or the like used to apply a biasing force to the resistance application member 17 may be separately provided.

With the configuration of the resistance application member 17 described above, provided that the flap seal 7 has been removed, the free end side of the resistance application member 17 moves downward from a position indicated by the chain double-dashed lines to a position indicated by dashed lines in the bag body 3 due to the biasing force, in accordance with the amount of reduction of the bulk of the wet wipe stacked body 5, as shown in FIG. 2. Therefore, even if the bulk of the wet wipe stacked body 5 is reduced, the resistance application member 17 is continuously pressed against the front surface of the wet wipe stacked body 5. That is, the resistance application member 17 is configured to be capable of biasing the wet wipe stacked body in such a way that at least a portion of the resistance application member 17 where the resistance application hole is formed moves in a direction in which the wet wipe stacked body 5 is biased, in accordance with the amount of reduction of the bulk of the wet wipe stacked body 5 resulting from pulling out the wet wipe continuous body 6 from the outlet port 16. Further, the resistance application member 17 is tilted relative to the pulling-out direction of the wet wipe continuous body 6 in a state in which the bulk of the wet wipe stacked body 5 is reduced. As a result, a strong frictional resistance force is applied to the wet wipe continuous body 6 from the resistance application hole 23, whereby a leading wet wipe of the wet wipe continuous body 6 can be separated and pulled out at an appropriate position. Note that FIG. 2 shows the state of the wet wipe packaging body 1 to which the flap seal 7 has been bonded. However, for the purpose of illustration, the above description on the movements of the resistance application member 17 is given assuming that the flap seal 7 has been removed.

The flange portion 13 is formed to outwardly project like a collar from the outlet port frame main body 11 in its radial direction. As shown in FIG. 2, the flange portion 13 has the first bonding surface 24 and the second bonding surface 25. The first bonding surface 24 is a surface bonded to an inner surface 3 b of the bag body 3 when the outlet port frame 4 is attached and fixed to the inner portion of the bag body 3. Further, the second bonding surface 25 is a surface bonded to an outer surface 3 a of the bag body 3 when the outlet port frame 4 is attached and fixed to the outer portion of the bag body 3. In the embodiment, the first bonding surface 24 is formed as the upper surface of the flange portion 13, and the second bonding surface 25 is formed as the lower surface of the flange portion 13. As shown in FIG. 2, when the outlet port frame 4 is fixed from the outer side of the bag body 3, the second bonding surface 25 is bonded to the outer surface 3 a of the bag body 3 by an adhesive, a gluing agent, or the like. The first bonding surface 24 and the second bonding surface 25 are preferably formed as flat surfaces. Since the first bonding surface 24 and the second bonding surface 25 are formed as flat surfaces, attachment strength for air-tightly attaching and fixing the outlet port frame 4 to the bag body 3 by bonding, heat sealing, or the like can be further increased. Further, the flange portion 13 is preferably formed over the entire periphery of the outlet port frame main body 11. Since the flange portion 13 is formed over the entire periphery of the outlet port frame main body 11, a larger area for bonding or the like can be secured and the attachment strength can be further increased.

The first bonding surface 24 of the flange portion 13 is preferably set at a position vertically lower than the upper surface 18 of the outlet port frame main body 11 in the height direction. This is because the peripheral wall portion 14 of the outlet port frame main body 11 projects outwardly from the bag body 3 via the opening portion 2 of the bag body 3 when the first bonding surface 24 is bonded to the inner surface 3 b of the bag body 3 to arrange the outlet port frame 4 on the inner side of the bag body 3, which facilitates the positioning of the outlet port frame 4 in the bag body 3. Further, the second bonding surface 25 of the flange portion 13 is preferably set at the same position as the lower surface 19 of the outlet port frame main body 11 or preferably set at a position lower than the lower surface 19 of the outlet port frame main body 11 in the height direction. That is, the lower surface 19 of the outlet port frame main body 11 is preferably set at a position not lower than the second bonding surface 25 in the height direction. This is because the flap seal 7 adhered so as to close the opening portion 2 of the bag body 3 or a portion subjected to a half-cut process can be prevented from being excessively pressed to open the opening portion 2 when the second bonding surface 25 is bonded to the outer surface 3 a of the bag body 3 to arrange the outlet port frame 4 on the outer side of the bag body 3, whereby air-tightness inside the wet wipe packaging body 1 that is not in use can be reliably maintained.

As shown in FIGS. 4 and 5, the outlet port frame 4 is configured to be capable of being arranged on the inner side of the bag body 3. When the outlet port frame 4 is arranged on the inner side of the bag body 3, the first bonding surface 24 of the flange portion 13 is air-tightly bonded to the inner surface 3 b of the bag body 3 by a method such as heat sealing and the second bonding surface 25 is arranged so as to face the wet wipe continuous body 6 on the inner side of the bag body 3. Further, the outlet port frame 4 is formed such that the peripheral wall portion 14 projects outwardly from the bag body 3 via the opening portion 2 of the bag body 3. In the cases of modes shown in FIGS. 4 and 5, the wet wipe packaging body 1 is tightly closed when the peripheral wall portion 14 of the outlet port frame main body 11 and the cover body 12 are fitted to each other. Therefore, unlike the above case in which the outlet port frame 4 is attached and fixed on the outer side of the bag body 3, the adhesion of the flap seal 7 to the opening portion 2 and the implementation of a half-cut process with respect to an area serving as the opening portion 2 of the bag body 3 can be eliminated.

Since the flange portion 13 of the outlet port frame 4 has the first bonding surface 24 and the second bonding surface 25 in the wet wipe packaging body 1 according to the embodiment, the outlet port frame 4 alone can be attached and fixed to both the outer surface 3 a and the inner surface 3 b of the bag body 3. Accordingly, the versatility of the outlet port frame 4 can be remarkably increased, and costs for manufacturing the wet wipe packaging body 1 and costs for managing and storing components can also be remarkably reduced. Further, thanks to the versatility of the outlet port frame 4, the management of the components can be facilitated and efforts and operation complexity in managing and storing the components can be solved.

Further, since the outlet port frame 4 can be attached and fixed to both the outer surface 3 a and the inner surface 3 b of the bag body 3 in the wet wipe packaging body 1 according to the embodiment, the wet wipe packaging body 1 can be manufactured while making use of each advantage of an outer bonding type and an inner bonding type. That is, in the case of the wet wipe packaging body 1 of the outer bonding type, the outlet port frame 4 is only required to be bonded to the outer surface 3 a of the bag body 3 by an adhesive, a gluing agent, or the like. Therefore, the wet wipe packaging body 1 of the outer bonding type offers an advantage in that it is easily manufactured and fit for mass production. Accordingly, for example, when there is a need for the mass production of the wet wipe packaging body 1, the outer bonding type may be selected. On the other hand, in the case of the wet wipe packaging body 1 of the outer bonding type, the flap seal 7, a half-cut process, or the like is required or an adhesive is required to attach the outlet port frame 4 to the bag body 3. That is, there is a likelihood that costs for manufacturing the wet wipe packaging body 1 of the outer bonding type are relatively increased. Accordingly, in a case in which the wet wipe packaging body 1 is manufactured with a view to reducing the manufacturing costs, the inner bonding type may be selected that does not require the flap seal 7 or the like and allows the attachment of the outlet port frame 4 to the bag body 3 by heat sealing that does not require an adhesive, a gluing agent, or the like.

As described above, in the wet wipe packaging body 1 according to the present invention, the outlet port frame 4 alone allows the arbitrary selection of a place to install the outlet port frame 4 in the bag body 3 and the extension of a selection range in manufacturing the wet wipe packaging body 1 with consideration given to the advantages of the outer bonding type and the inner bonding type.

The above embodiment shows an example in which the opening portion 2 of the bag body 3 is configured to be tightly closed by the flap seal 7 and the flap seal 7 is peeled in use. However, the opening portion 2 may be configured to be tightly closed by a seal in a half-cut state and opened by pressing or peeling a half-cut portion into or from the bag body 3 in use. Further, the opening portion 2 can also be configured such that the outlet port 16 of the outlet port frame 4 is tightly closed by a pull-top cover instead of the flap seal 7 and the pull-top cover is pulled out to open the opening portion 2 in use.

Further, the embodiment shows a case in which the resistance application member 17, one end side of which serving as a support end is supported by the outlet port frame 4, is brought into a cantilevered state. However, as shown in FIGS. 5A to 5D, the resistance application member 17 may be brought into a so-called both-end support state in which the both ends of the resistance application member 17 are fixed to the outlet port frame 4. As shown in, for example, FIG. 5A, the both ends of the resistance application member 17 may be attached to a pleated portion 31 fixed to the outlet port frame 4 such that the resistance application member 17 is biased by the restoration force of the compressed pleated portion 31. Further, as shown in FIG. 5B, the both ends of the resistance application member 17 may be respectively fixed to the first ends of springs 32, second ends of which are fixed to the outlet port frame 4, such that the resistance application member 17 is biased by the restoration force of the compressed springs 32. Further, as shown in FIG. 5C, the resistance application member 17 may be fixed to elastic bodies 33 instead of springs such that the resistance application member 17 is biased by the restoration force of the elastic bodies 33 compressed so as to curve. Further, as shown in FIG. 5D, rod-shaped supporting bodies 34 made of elastic bodies or the like may be attached to the outlet port frame 4 at their folded ends on one side and fixed to the resistance application member 17 at their ends on the other side such that the resistance application member 17 is biased by a restoration force generated when the compressed folded portions are compressed. Examples of the above elastic bodies include, but not limited to, rubber, plastic, or the like so long as they are made of materials having elasticity. However, rubber and plastic are generally preferable. Note that in a case in which the resistance application member 17 is brought into a both-end support state as shown in FIGS. 5A to 5D in the wet wipe packaging body of the outer bonding type, the opening portion 2 of the bag body 3 is preferably configured to be tightly closed by a seal in a half-cut state and opened by pressing or peeling a half-cut portion into or from the bag body 3, or the opening portion 2 is preferably configured such that the outlet port 16 of the outlet port frame 4 is tightly closed by a pull-top cover and the pull-top cover is pulled out to open the opening portion 2. Further, in this case, the second bonding surface 25 of the outlet port frame 4 is attached and fixed to the outer surface 3 a of the bag body 3 by an adhesive, a gluing agent, or the like.

Further, in a case in which the resistance application member 17 is brought into the both-end support state as shown in FIGS. 5A to 5D in the wet wipe packaging body of the inner bonding type, the outlet port frame 4 having the resistance application member 17 is attached by a method such as heat sealing. At this time, the first bonding surface 24 of the outlet port frame 4 is bonded to the inner surface of the bag body by heat sealing or the like. In the case of the wet wipe packaging body of the inner bonding type, the peripheral wall portion of the outlet port frame is arranged so as to project outwardly from the bag body via the opening portion of the bag body. Therefore, air-tightness inside the bag body can be maintained when the cover body is closed. Accordingly, the wet wipe packaging body of the inner bonding type does not require the adhesion of the flap seal to the opening portion and the implementation of a half-cut process or the like with respect to the opening portion of the bag body, but can maintain air-tightness inside the bag body under better conditions only by the opening and closing operations of the cover body.
